Patented March 12, 1907- Application filed November 12. 1906. Serial No.343,122.

T0 all whom, t may concern/.-

, Be it known that I, ELMER R. CONNELL, a citizen of the United States,residing at Keyser, in the county of Mineral and State of West Virginia,have invented a new and useful Clock, of which the following is aspeciication.

This invention relates to striking clocks, and has for its principalobject to provide a means in the nature of an attachment which may beapplied to existing clocks for the purpose of more fully designating thetime at the half-hours.

A further object ofthe invention is to provide an attachment forordinary ,clocks which strike both the hour and half-hour, by whichafter the single stroke denoting the half-hour a separate gong willsound the full hour.

With these and other objects in view, as will more fully hereinafterappear, the invention consists in certain novel features of constructionand arrangement of parts hereinafter fully described, illustrated in theaccompanying drawings, and particularly` pointed out in the appendedclaim, it being understood that various changes in the form,proportions, size, and minor details of the structure may be madewithout departing from the spirit or sacri'licing any of the advantagesof the invention.

In the accompanying drawings, Figure 1 is a front elevation of astriking clock provided with an auxiliary striking means arranged andconstructed in accordance with the invention. Fig. 2 is a detail viewillustrating merely the arrangement ofthe striking-levers and theirconnections. Fig. 3 is a detail view of a portion of the attachmentlooking from the rear.

Similar numerals of reference are employed to indicate correspondingparts throughout the several iigures of the drawin s.

In Fig.. l is illustrated an ordinary eightday clock A, having a gong B,which is struck by a hammer C at each hour and once at each half-hour.The hour periods are under the control of a striking-wheel D, which isengaged by a lever E, the latter being moved to release position by asmall crank F, carried by the main arbor G. At the end of the half-hourperiods the crank F engages a lever Hwhich is connected to and operatesthe hammer C in the usual manner. In addition to this mechanism anauxiliary striking-train I is employed, this mechanism including astriker-wheel J, a lever K, a hammer L, and gong M, the latter beingdiiferent in tone from the gong B. The main arbor G is preferablyextended some little distance beyond the back of the mainframe, and toits outer end is adjustably secured a crank-arm 10, the latter beinglocked in place by a setscrew 11, so that it may be revolubly adjustedand made to correspond accurately to the main crank F. This crank 10 isarranged to engage a lever 12, that is mounted on a pivotpin 13, carriedby a disk 14 at the rear of the frame, and said lever is connected by anarm 15 to a crank-arm 16, that is carried by a loose arbor 17, saidarbor 17 being provided with an adjustable rocker-arm 18, that isenranged to engage the controlling or locking lever K of thestriker-wheel J. l

In operation the main clock mechanism will operate in the usual mannerat the end of each hour to allow the hammer C to strike the gong D, andat the end of each half-hour the crank F will engage the arm Hand afterwiping past the latter the hammer C will be moved against the gong D,the hammer making but a single stroke to denote the halfhour, as usual.At the same time the crank F leaves the arm H the auxiliary crank 10will have engaged the lever 12, and forcing the latter down against thestress of the spring 20, and its movement will be transmitted, throughthe rod 15, to the arm 16, rocking the arbor 17, and the rocker-arm 18will then lift the lever K of the auxiliary striking-train, so that thelatter will operate on the hammer L and the gong M will be sounded anumber of times corresponding to the previous hour, or, in other words,if the time be half-past three the hammer C will make one stroke,

and then the hammer L will make three strokes, so that the time will beclearly noticed, and as the gangs difler in tone there can be noconfusion in the reading of the time.

The disk 14, which carries the pivot-pin 13, is revolubly adjustable, sothat the secondary striking-train'may be placed in any position withreference to the main clock in accordance with the size of theclock-casing or the construction and arrangement of the parts, thisbeing especially valuablewhere the device is used in connection withtower-clocks and the like.

I clairn- An attachment for striking clocks of that IOO IIO

Glass in which both the liour and half-hour are sounded, comprising anauxiliary gong, an auxiliary hammer, an auxiliary strikingtrain, aControlling-lever for the latter, a rocker-arm 'for operating saidlever, an arbor carrying said rocker-arm, a crank-pin on the arbor, aCrank-pin adjnstably secured to the main arbor of the clock, a diskadjustably mounted at a point adj aeent to the arbor, a pivot-pinCarried by the disk, a lever mounted on the pvot-pin and arranged to beengaged by the adjustable crank, and a connecting-rod extending betweenthe disk-earried lever and the arbor Crank-pin.

In testimony that I Claim the foregoing as my own I have liereto allixedmy signature in the presence of two Witnesses.
